Question
Two cylinders act right after one another. Each cylinder is metered, and some actions are slow, and there is a dwell between some
actions. What is the minimum flow rate required (CFM) to operate this cylinders? (enter answer with 2 decimal places)
Sequence of operations:
Cyl. A extends with metering (takes 1.5 second)
Dwell time for 2 seconds for part machining
Cyl. B extend and retracts without metering (2 second)
Dwell time for 10 seconds while an electric mixer is operated
Cyl. A retracts quicky with no metering (0.5 seconds)
Dwell time for 5 seconds while a part is placed before next cycle
Assuming the displacements of the cylinders are:
Cyl. A DE 65 in³
=
Cyl. A DR = 62 in³
=
Cyl. B DE 44 in³
Cyl. B DR=41 in³
